The metabolism of an animal is estimated by determining rates of carbon dioxide production (VCO2) and oxygen consumption (VO2) of individual animals, either in a closed or an open-circuit respirometry system. Two measures are typically obtained: standard (SMR) or basal metabolic rate (BMR) and maximal rate (VO2max). SMR is measured while the animal is at rest (but not asleep) under specific laboratory (temperature, hydration) and subject-specific conditions (e.g., … WebRespirometers are devices that measure gas volume changes, and therefore can provide information about the rate of cellular respiration STUDY HOW WE SET UP THE RESPIROMETER For this respirometer yeast and a sugar solution will be placed in one test tube, with a piece of flexible hosing coming out of the cork (Fig. 3). list learned competencies
